Definitions

  • the present invention is directed to a steel sheet pile for forming the wall of an excavation, the sheet piling assembly formed of a plurality of the steel sheet piles and the method of construction the assembly.
  • Figs. 1 and 2 there have been widely utilized for the construction of such sheetpiling wall channel steel piles 1 with joint elements 2 at their side edges or H steel piles 3 with joint elements 4 at the side edges of each of opposed flanges 5 of equal width.
  • These piles 1 and 3 are in use to be driven into the ground in side edge to side edge relationship with the joints elements interconnecting the adjacent piles.
  • the H steel piles 3 are found to be advantageous over the channel piles 1 from an economical standpoint since they have inherent rigidity higher than the channel piles with respect to unit weight and can be designed in less weight or thickness for the same rigidity required in constructing the sheetpiling wall.
  • H steel piles 3 are designed to be arranged in a straight line along the wall of an excavation such as a trench and a well and therefore find themselves impossible in some situations to be placed along a curved portion and a corner portion of the wall, because the remaining flanges 5 that do not act as the joint will certainly jam with each other when the piles 3 are required to be placed with little intervening space therebetween, as shown in Fig. 3, to prohibit an angled positioning of the H steel pile in relation to the adjacent piles. That is, the prior H piles 3 can be angularly disposed with each other only with considerable spaces therebetween which could weaken the sheet piling wall assembly to an unusable extent.
  • H steel pile 3 will sometimes incur a problem that the web 6 of each H steel pile 3 traverses the ground so as to divide the ground into separate portions, resulting in less binding forces between the individual portions of the ground on both sides of each web 6 and between the pile 3 and the ground.
  • the above drawbacks have been eliminated by the present invention which provides a steel sheet pile of unique and useful configuration for forming the wall of an excavation.
  • the sheet piles are driven into the ground in side edge to side edge relationship to form the wall in the ground.
  • Each of said sheet piles has a generally H-shaped cross section comprising a web with a wide flange on one side thereof and a narrow flange on the opposite side. Formed at the side edges of the wide flange are joint elements which interconnect the adjacent pairs of sheet piles and which allow a limited angular disposition of an individual sheet pile relative to the adjacent sheet pile.
  • the sheet piles With this configuration of the sheet pile having the wide and narrow flanges in addition to the joint construction of allowing the angular disposition of the sheet pile, the sheet piles can be successfully placed along a curved wall or at a corner portion thereof without requiring considerable intervening spaces between the adjacent sheet piles.
  • each sheet pile Formed in the web of each sheet pile are a series of longitudinally spaced perforations through which the soil of the ground or the like can pass for assuring strong binding of the soil or the like between the portions on both sides of the web and strong binding between the individual piles and the ground.
  • the sheet pile is formed at its wide flange with an integral rib of generally U-shaped configuration for increasing the mechanical strength of each sheet pile.
  • a method of forming such cutoff wall comprises the steps of forming a loose or unsolidified grout curtain in the ground with that grout material, driving the sheet piles into the loose grout curtain in such a way as to form a continuous sheet pile assembly by connecting the joint elements of the adjacent sheet piles and to permit the grout material to pass through the perforations in the web of each sheet pile, and allowing the loose grout curtain to dry for solidification.
  • the sheet piles can be sink in the ground under their own weight or aided by a slight push, enabling the sheet piles to be driven with a greatly reduced noise emission.
  • the sheet piles serve to be the core of the solidified grout curtain so as to form therewith the consolidated cutoff wall.
  • a sheet pile assembly 10 which is combined with a grout curtain 30 in the ground to form a cofferdam or a cutoff wall of an excavation such as a trench and a well.
  • the sheet pile assembly 10 consists of a series of sheet piles 11 arranged in side edge to side edge relationship with each other to extend along a straight or curved line.
  • Each of the sheet piles 11 is in the form of a generally H-shaped cross section along the entire length thereof comprising a web 12 with a wide flange 13 on one side thereof and a narrow flange 14 on the other side.
  • joint elements 15 and 16 are U -shaped return hooks, one up-turned and the other down-turned to have their openings facing in opposite directions.
  • Such construction of the joint elements 15 and 16 is conventional and permits the adjacent sheet piles 11 to be interconnected in mutually slidable edge-engagement for facilitating the placement of the sheet piles 11 in addition to that it permits a limited angular disposition of the individual sheet pile 11 relative to the adjacent one.
  • the members of the sheet pile 11 employed in the embodiment is dimensioned for example such that width A of web 12, width B of wide flange 13 and width C of narrow flange 14 are 400, 600 and 200 mm and that thickness T 1 of web 12, thickness T 2 of wide flange 13 and thickness T 3 of narrow flange 14 are 4.5, 6 and 18 mm.
  • the sheet pile of the present invention should not limited to the above dimensional feature except that the narrow flange 14 has a width preferably a half or less of the wide flange 13.
  • Formed in the web 12 are a series of longitudinally spaced perforations 18 which are trapezoid with one side thereof along the intersection between the web 12 and the wide flange 13. It is of course that the configuration and location of the perforations 18 should not limited to the above and may take the forms as illustrated in Figs. 8A and 8B.
  • Fig. 9 shows a modification of the above sheet pile which is similar to the above except that a sheet pile 21 is formed at its wide flange 23 with an integral rib 27 which is generally U -shaped in cross section and extends longitudinally along the intersection of a web 22 and the wide flange 23 for reinforcement of the sheet piles.
  • Such reinforcing rib 27 may be formed at a portion other than that intersection but within the width of the wide flange 23..
  • the sheet pile assembly 10 of the present embodiment is placed in a grout curtain 30 formed in the ground and cooperative therewith to form a cutoff wall around an excavation.
  • Said grout curtain 30 is made of a grout material such as soil-cement or soil-bentonite-cement mixture filled within a ditch 31 defined by a series of consecutive holes 32 dug in the ground.
  • a drilling derrick 40 having three parallel auger shafts 41, as shown in Figs. 10 and 11, is employed for digging the ditch 31 or the holes 32.
  • the drilling derrick 40 is carried by a crawler crane 42 for easy location thereof.
  • Each of the auger shafts 41 is provided at its tip with a nozzle 43 for injecting cement paste with bentonite added thereto or not.
  • the cement paste injected from the nozzle 42 will be mixed homogeneously with the remaining soil in the holes 32 by the action of the spirals on the auger shafts 41 as the drilling goes on so as to provide a soil-cement or soil-bentonite-cement mixture which defines said grout material for the grout curtain 30.
  • FIG. 13 illustrates a sequence of constructing the above sheet pile assembly 10 from the drilling of the holes 32 to driving of the sheet piles 11 thereinto, from which it is understood that the drilling of holes 32 and filling of the grout material into the holes 32 or ditch 31 are performed within one cycle from diving the auger shafts 41 into the ground to extracting the same from the ground. Accordingly, the holes 32 filled with the grout material is formed within one operational cycle of the drilling derrick 40. Said trench 31 is made by successively performing the above drilling operation in such a manner as to make a required configuration along the perimeter of the excavation to be dug, which simultaneously forms the loose or unsolidified grout curtain 30 of the required configuration in the ground.
  • said sheet piles 11 are successively inserted in the curtain 30 under their own weights or aided by a slight force applied to the top thereof.
  • the joint elements 15 and 16 can be slid one within the other so as to interconnect the adjacent sheet piles 11 within the loose grout curtain 30, as shown in Fig. 12B, while the grout material can readily permeate in the joint portions between the adjacent joint elements 15 and 16 such that it can securely link the adjacent ones of the sheet piles 11.
  • the sheet piles 11 are successively driven into the loose grout curtain 30 to extend therealong.
  • the sectional configuration of the sheet pile 11 allows the individual sheet pile 11 to be displaced angularly relative to the adjacent ones without the interference between the narrow flanges 14 of the adjacent sheet piles 11, whereby the sheet pile assembly can conform with not only a straight line but also a curved line or can make a corner portion, as shown in Fig. 4.
  • the sheet pile assembly 10 is fixedly installed in the curtain 30 to form therewith the cutoff wall in which the assembly 10 acts as a core structure.
  • Said perforations 18 in the web 12 of each sheet pile 11 allow the grout material to pass therethrough for assuring strong binding force developed between the portions of the grout curtain 30 on both sides of the web 12 of each sheet piles 11, which in turn assures a strong combining force between the sheet pile assembly 10 and the surrounding grout curtain 30.
